United States Patent() LINING FOR WATER-PROOF CLOTHING Hans Klepper,Rosenheim, Upper Bavaria, Germany Application September 6, 1956, SerialNo. 608,300 Claims priority, application Germany December 29, 1.955 p 7Claims. (Cl. 2'-97) .The present invention relates to a novel liningforwater-proof material as well as to the combination of water-proof outerclothing with the novel lining.

A disadvantage attending use of water-proof clothing formed ofimpervious sheet material such as rubber resides in the fact that watervapor within the clothing has no opportunity to escape and thuscondenses on the inside surface. Activity on the part of the wearerresults in perspiration which aggravates the problem so that the weareris extremely uncomfortable.

As a partial solution it is possible to aflix spacers to the undersideof the clothing so that the clothing will not be held directly againstthe body and so that room will be provided for the circulation of airbetween the body and the clothing, thereby removing excess water vaporand condensed moisture. To this end the water-proof material may beprovided with spaced webs or strips of fabric on its underside to formlongitudinally extending channels running from top to bottom.

Even so the problem is not satisfactorily solved since the points wherethe spacer webs contact the body are not subjected to circulation ofair. If the strips are made narrow and spaced a considerable distanceapart in order to have less contact with the body, then the waterproofmaterial is free to sag and thereby reduce the cross-section of the airchannels. In addition, the sagging waterproof material may directlycontact the body intermediate the spacers.

It is accordingly an object of the present invention to provide a liningsuitable for water-proof clothing, which lining will substantiallyeliminate condensation of water on the underside of the clothing.

Another object of the invention is to provide a lining for water-proofclothing which will permit circulation of air and which will preventaccumulation of moisture-laden air substantially everywhere between thebody and the outer fabric.

These and other objects and advantages are realized in accordance withthe present invention wherein there is provided a lining composed ofspaced pieces of porous cellular material held together by a loosematrix or lattice of weaving or knitting rthreads. The cellular materialmay comprise natural or synthetic rubber which has been foamed orotherwise formed into a sponge and can be formed either as a pluralityof parallel strips or a checkerboard arrangement of pieces held inposition by cross-threads.

Thus, even if the sponge rubber of the lining contacts the body over anappreciable area circulation of air will still be possible due to theporosity and permeability of the sponge rubber to air. In addition, thesponge rubber is moisture absorbent and thus can take up any excessmoisture so as to prevent condensation or minimize the discomfortotherwise attending such condensation.

The invention will now be described more fully with yreference to theaccompanying drawing, wherein:

Fig. 2 is a section taken along line lI--II of Fig. l.

Fig. 3 is an elevation of a lining made in accordance with theinvention, showing a checkerboard arrangement of pads.

Fig. 4 is an elevation of a coat showing the lining of Figure 3 appliedthereto, and

Fig. 5 shows the lining of Figure 2 without the clothmg.

Referring now more particularly tto the drawing, there is shown a pieceof clothing 1 formed of water-proof material such as rubber orrubberized textile material. The inside of the clothing 1'is providedwith a lining Z which may be aiixed tothe water-proof material by anadhesive, by sewing in along the seams, or the like. Alternatively, thelining 2 may be independent of the clothing 1 and may be put onseparately as an undergarment.

The lining may be coextensive with the clothing 1 or as shown may onlybe provided for certain parts of the body which would normally come incontact with the clothing when worn, such as across the shoulders, chestand possibly the arms.

The lining 2 consists of a loose or open weaving or knitting into whichspaced strips 3 of foam or sponge rubber or other porous cellularpolymeric material are incorporated. The positioning is effected bycross-threads 4 extending transversely which are connected withlongitudinally extending threads or chains of stitches 6. Between thefirst and second chains 6 a sponge rubber strip 3 is inserted and isheld in place due to the fact that some threads 4 pass in front of thestrip 3 and others behind the strip. Between the second and third chains6 the cross-threads 4 -do not contact any sponge rubber inserts and thussubstantially unimpaired channels 5 are formed, alternated with thestrips 3.

The sponge rubber pieces permit a ready circulation of air through thelongitudinal channels 5 and because of their porosity take up excesswater vapor and/ or condensed moisture. When the formation of watervapor is reduced as during rest, the circulating air can then remove anyWater previously absorbed by the sponge rubber. Because of the porouscellular nature of the sponge rubber, the cross-section of the channels5 can be relatively small compared to the width of the strips 3 and airWill still be capable of circulating. The sponge rubber spacers can alsobe laid out in other patterns, such as a checkerboard, with the pieceseither spaced from each other or contacting each other at the corners.In the latter case, circulation of air will still be possible because ofits ability to pass through the cellular pieces.

Various changes and modifications may be made without departing from thespirit and scope of the present invention and it is intended that suchobvious changes and modifications be embraced by the annexed claims.

What is claimed is:
